CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of Ser. No. 14/969,244, filed Dec. 15, 2015, which claims priority to and the benefits of priority to Chinese Patent Application No. 201410785058.1, filed Dec. 16, 2014. The contents of the aforementioned applications are incorporated herein by reference in their entireties.

TECHNICAL FIELD

The present application relates to the field of computer technologies, and in particular, to a method and an apparatus for displaying information.

BACKGROUND

With the development of information technologies, Digital Object Unique Identifiers (DOIs), such as barcodes, originated from a digital resource identification technology, are widely applied. A DOI is a code pattern formed by specific geometric figures (such as rectangles and squares). DOIs may include: one-dimensional barcode, two-dimensional barcode (also referred to as two-dimensional code), and the like. The DOI presents, in a graphic form, various encoded “intangible” information such as Internet link information, product information, or text information. A user can use a device to scan and identify the DOI, thereby acquiring information contained in the DOI.

A website provider can provide users with DOI-form information on a web site. For example, a DOI can be displayed on a page of a website, and after a user uses a device having a camera function (for example, a smartphone, a tablet computer, or other terminal devices) to scan the DOI, the device can read information in the DOI. For example, Internet link information may be embedded in a two-dimensional code and a user may use a device to read the link information in the two-dimensional code.

In the mechanism described above, a user generally needs two devices to perform the function. Specifically, one device is used to display a website page containing the DOI, and the other device is used to scan the displayed DOI. In the device for displaying the DOI, a cursor or another window on the page may obscure an area where the DOI is displayed, and when the DOI is obscured, the process of scanning the DOI will be affected, or even worse, the scanning device may fail to read the DOI.

DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatus and methods consistent with aspects related to the invention as recited in the appended claims.

The present disclosure provides a method for displaying information on a webpage. FIG. 1 shows one embodiment of an information display process of the present disclosure. As shown in FIG. 1, the process may include the following steps.

S101: monitor a display position of a DOI and a display position of other information on a page.

In some embodiments of the present application, the DOI may include, but is not limited to: graphic identifiers such as a barcode or a two-dimensional code. The page may be one of various interfaces that contain the DOI, for example, a website page, an application page, or a floating window. The page may be displayed by a terminal device having a display function, for example, a computer, a tablet computer, or a smartphone.

In one embodiment, the other information described above may be an image, text, or other objects that may obscure the DOI. For example, the other information may be a cursor. The cursor may have various graphic structures for indicating a control position, for example, a mouse pointer. The page may include various display information, and the display information may be displayed on the page in a popup or hover manner, for example, a popup window, a hover picture, or a hover Flash animation. The other information may include, but is not limited to, at least one of a cursor, a popup window, and a floating window.

In actual applications, when a user uses a terminal device to open a page, a DOI and other information on the page may be embedded in the page or hover on the page. In some manner, the terminal device displays the DOI and other information only when the DOI and other information appear in a display window (for example, a browser window or a terminal screen) of the terminal device. The display position of the DOI and the display position of the other information in the present application refer to positions where the DOI and other information are displayed when they appear in the display window.

When the other information described above is displayed on the page, the other information may obscure or even completely cover the DOI. That is, the display position of the other information overlaps the display position of the DOI. Consequently, the DOI cannot be clearly displayed on the page. In this scenario, the terminal device for reading the DOI cannot read the information in the DOI.

For example, as shown in FIG. 2, the page is displayed in a display window of the terminal device. On the page, the DOI is a two-dimensional code, and the other information is a hover picture. The hover picture is currently suspended above the two-dimensional code, and obscures a part of the two-dimensional code. As a result, other terminal devices cannot read information in the two-dimensional code.

Therefore, in one embodiment of the present application, the terminal device, which displays the DOI, can monitor the display position of the DOI and the display position of the other information on the page, and detect whether the display position of the DOI overlaps the display position of the other information. In some embodiments, the display position of the DOI and the other information can be represented by coordinates. The terminal device, which displays the page, can detect whether the coordinates of the DOI superimpose on the coordinates of the other information (for example, whether they have the same X-Y coordinates).

S102: when it is detected that the display position of the other information overlaps the display position of the DOI, the terminal device performs a hiding process on the other information.

Consistent with some embodiments, when the terminal device detects that coordinate sets of the display position of the DOI and the other information superimpose with each other, it can be assumed that the display position of the other information overlaps the display position of the DOI. To ensure that the DOI can be clearly displayed on the page, the terminal device can perform the hiding process on the other information, so that the DOI can be displayed at the top layer and is not obscured. In this way, other terminal devices can accurately scan the DOI, and thus improves the DOI reading efficiency.

In step S101 shown in FIG. 1, the terminal device may monitor the display positions of the DOI and other information on the page by using a JavaScript program. Specifically, an application in the terminal device may monitor the display positions of the DOI and other information. The application includes, but is not limited to, various programs, including the JavaScript program, that are installed in the terminal device and have a page display function, for example, a browser and a player. The JavaScript program may be embedded in the page.

During the monitoring process, specific display positions of the DOI and other information may be reflected by a series of coordinates (in other words, coordinate sets). With the JavaScript program, it can be detected in real time whether some of the coordinate sets of the display positions of the DOI and other information superimpose on each other (e.g., whether the DOI and the other information have identical coordinate sets), to determine whether the display position of the DOI overlaps the display position of the other information.

Continuing with the above example, in the two-dimensional code in FIG. 2, coordinates corresponding to two upper vertexes A1 and A2 are as shown in the figure, and coordinates of two lower vertexes A3 and A4 (not shown in FIG. 2 because they are covered by the hover picture) are (20,10) and (30,10), respectively. The coordinates of four vertexes B1 to B4 of the hover picture are shown in FIG. 2. From the coordinates of the vertexes, it can be seen that the hover picture overlaps the two-dimensional code.

In the present application, the coordinate sets of the DOI and other information may be determined by many mechanisms, for example, acquiring corresponding coordinate information by reading an HTML (HyperText Mark-up Language) source file of the page, or acquiring coordinate information of a target area after identifying images in content in the display window. The present application is not limited to any specific mechanism. The DOI and the other information, when displayed, may have irregular shapes. By comparing the coordinates (e.g., of the pixels), the terminal device can determine which portion of the DOI and the other information overlap.

As discussed above, the JavaScript program may be used to adjust various dynamic functions (including a display manner, a display state, and the like of the information displayed on the page) on the page. In some embodiments of the present application, the JavaScript program may further be used to perform the hiding process on the other information. In other words, in some embodiments of the present application, the JavaScript program not only can monitor the display positions of the DOI and other information, but also can perform the hiding process on the other information.

In some embodiments, the hiding process on the other information may include hiding, at least a portion of the other information by, e.g., adjusting the transparency of the portion of the other information, to expose the DOI. In one exemplary embodiment of the present application, an application in the terminal device may acquire an Alpha Channel corresponding to the other information by reading an HTML source file of the page with the JavaScript program, and adjust a gray value in the Alpha Channel, to maximize the transparency of the other information. In some embodiments, by adjusting the gray value, the terminal device can make the other information become completely transparent.

For example, continuing with the above example, because the hover picture obscures the two-dimensional code on the page shown in FIG. 2, the application in the terminal device may acquire an Alpha Channel corresponding to the hover picture, and adjust a gray value in the Alpha Channel, to make the hover picture completely transparent, as shown in FIG. 3. After the adjustment, the two-dimensional code is clearly displayed on the page.

In another exemplary embodiment of the present application, the hiding process on the other information may include determining an overlap area between the display position of the other information and the display position of the DOI, and adjusting the transparency of the overlapping area in the display position of the other information. In other words, in this embodiment, the other information is not hidden completely; instead, only the area overlapping the DOI is hidden. The overlapping area may also be determined according to the coordinate sets, and specifically, the overlapping area is an area corresponding to the superimposition between a coordinate set of a display area of the DOI and a coordinate set of a display area of the other information.

For example, in FIG. 2, an overlap area between the hover picture and the two-dimensional code is determined according to the coordinates of the two-dimensional code and the hover picture, and then, the hover picture in the overlapping area may be hidden by adjusting the transparency of the overlapping area in the hover picture, as shown in FIG. 4.

In some other embodiments, the terminal device may display the DOI on top of the other information, so that the other information does not obscure the DOI.

Through the foregoing steps, during scan of the DOI, the JavaScript program is used to monitor the display position of the DOI on the page, and if it is detected that the other information on the page obscures the DOI, at least a part of the other information is hidden, so that the DOI is displayed clearly, thereby effectively improving the DOI reading efficiency, and avoiding the problem that the DOI cannot be read because the other information on the page obscures the DOI.

The present disclosure further provides an apparatus for displaying information, as shown in FIG. 5. As shown in FIG. 5, a terminal device for displaying information may include a monitor module 501 and a processing module 502.

The monitor module 501 is configured to monitor a display position of a DOI and a display position of other information on a page (e.g., a webpage). The DOI includes, but is not limited to: graphic identifiers such as a barcode or a two-dimensional code. The other information includes, but is not limited to, at least one of a cursor, a popup window, or a floating window. In some embodiments, the monitor module 501 includes a JavaScript program configured to monitor the display position of the DOI and the display position of other information on the page.

The processing module 502 is configured to perform a hiding process on the other information when it is detected that the display position of the other information overlaps the display position of the DOI. In some embodiments, the processing module 502 includes or is configured to execute a JavaScript program configured to perform the hiding process on the other information. In some embodiments, the processing module 502 is configured to hide the other information by adjusting the transparency of the other information. In some other embodiments of the present application, the processing module 502 is configured to determine an overlapping area between the display position of the other information and the display position of the DOI, and adjust the transparency of the overlapping area in the display position of the other information, so that the overlapping area in the other information does not obscure the DOI.
